by and large, you have a few that are using them in an active way, warehouse building, private homes. >> but a point of clarification, are they not acceptable or not available to certain other areas of the city and the business yes in those areas, because the beat is -- perhaps we don't know who opens the beat, but the person who does own the beat has just allowed it to become inactive. the special patrols that belong on the all-in-one beat can't provide services in a beat they don't own or what. >> they can share the beat, but it has to be authorized. >> by the beat owner? >> yes. >> if an area doesn't have an active beat or someone actively working in it, they can't call up an individual patrol special and ask them to come and be there person unless they have a guard card, and there are many other guard cards across the city. they can phone up and say, can you come and watch my building. can you stand guard at my a.t.m.? they can get the services, but not the ones labeling themselves patrol specialists. >> can we have an exact number of patrol specials and patrol systems out there?
